Strobe Device and Charging Control Method Therefor

A strobe device comprising:

• a battery case configured to hold a plurality of batteries formed in a substantially same size in a replaceable manner;
• a main capacitor configured to be charged by the batteries;
• a flash discharge tube to which a voltage is applied by the main capacitor;
• a voltage detecting unit configured to detect a voltage of each of the batteries, respectively;
• and
• a charging control unit configured to
• control charging of the main capacitor such that the main capacitor is charged with a first electric current that is suitable for lithium batteries in a case where a total voltage of the batteries detected by the voltage detecting unit is more than a prescribed first value and a difference in the voltage between the batteries is equal to or less than a prescribed value, and
• control charging of the main capacitor such that the main capacitor is charged with a second electric current that is greater than the first electric current in a case where the total voltage is equal to or less than the first value.
